JULIUS I-I. SCHLAFLY, OF CANTON, OHIO.

METALLIC FLU'ME.

Specicatioii of Letters Patent.

Application i'led November 23, 1911. Serial No. 661,985. f

i To all whom 'it may concern Be it known that I, JULrUs H. SCHLAFLY, a citizen of the United States, residing at Canton, in the county ofStark and yState of Ohio, have invented certain new and useful Improvements in Metallic Flumes; and I do hereby declare that the following is a Jiull, clear, and exact description of the in-v vention, such as will enable others skilled in the art yto which it belongs to4 make and use the saine. y

The present invention relates to lumes,l especially designed for water troughs used for irrigating and analogous purposes.`

The objects of the present invention are,

Y first, to provide a flume made up of sec-j tions `of suoli a length or lengths that can be conveniently shipped -and placed in position. Second, to provide means for soy connecting the sections together that the entire length of the trough or iiurne will present an even4 and smooth surface. Third, to provide means forsecurely clamping the joined ends of the sections together and in suoli a manner that they willA not be liable to become detached Jfrom any ordinary cause. Fourth, to provide means for adjusting the tro-ugl'i`with` kreference to its supports or hangers, and at the same time adjust the trough from time to time at such places as may be necessary or movement of the supporting traine.

With these objects together with others the invention consists in the construction and `arrangement of the parts as will be hereinafter more fully described and illustrated in the drawings.

In the accompanying drawings, Figure 1 is a perspective view showing portions of two sections and one full section, one completed joint and hanger, also one joint and its dierent parts disconnected. Fig. 2 is a longitudinal section on line 2-2, of Fig.

3. .'Figq is a transverse section on line 8-3, of Fig. 2. Fig. 4 is an enlarged fragmentary sectional view on line Alfil, Fig. 3. Fig. 5 is a longitudinal section showing one Inodiication of joint. Fig. 6 is a longitudinal section sho-wing still another or second modification of joint. Fig. 7 is a longitudinal section showing a third modification of the joint. Fig. S is a transverse section on line 8-8, Fig.-7. j

Similar numerals of reference indicate corresponding parts in all the figures ofthe drawings.

by reason of any sagging In the accompanying drawing, 1 represents the sections which. are preferably formed of sheet metal and arey seini-cylindricalin cross section. The sections may be formed of any desired length, reference being had to convenience in manufacture, shipping and assembling. The sections may be formed of various sizes, yreference being had to the capacity of theiinished trough.A

In use, especially for irrigating it frevarious sections going to make up the completed structure above l,the ground, as for instance it is desired to conduct water across a valley or depression and at the `same time maintain the proper grade orinclination so that water may be if necessary carried over elevations. In order to accomplish this result it is `frequently necessary to construct -trestle work or other framework ofconsiderable height and at other points lsuch trestle or traine work may be comparatively low, but as' arule the trough is to be supported throughout its entire length by suit-v Patented Oct. 13, 1914.`

`zojuently'is necessary to construct a trough ,i i

of considerable length and to support' the:

able cross bars or hangers 2 which cross bars y or hangers are supported by vsuitable frame' work or walls as the case may be. As shown the sections which` are non-corrugated are preferably formed without cor-y rug-ations sothat ythebottoin koit the trough or the surface. upon which the water flows is smooth, lthereby offering the least resistance to the flow of water. f

For the purpose of joining the sections together the ends of the sections are proj vided with the semi-circular channels 3 -and the channel portions lapped one upon the other, the extended or' outer portion 4C titf ting into the channel portion oan adjacent.

section. The inner clamping bar 5 is located in the'channel of the end of the sectionseated in or lapped in the adjacent section as illustrated in Fig. 2. rlhe outer clamping bottom or underside of the underlapped section. kThis outer clamping bar or yoke is screw threaded at its ends, which screw threaded portionsare passed through `suit-y able apertures ormed in the hangers 2. Upon the screw threaded kportions of the' yoke G are located the tie-blocks 7, the nuts 8, 9 and l0. The tie blocks 7 are provided with the grooves 11,. which grooves receive the topor upper ends of the `inner clamping bar 5, and the screw threaded ends `of the ioo yoke 6 pass through the apertures 12 formed in said tie-blocks. The nuts 8 are located upon the tie-blocks and arefor the purpose of securely holding said tie-blocks in proper relative position. The nuts 9 are for the purpose of forming rests or seats for the hanger bars 2, directly above the connected ends o-f the yoke 6. The nuts 10 which are located above the hanger bars 2 are for the purpose of holding the flume or trough sections in proper relative position with reference to the hanger bars 2. If desired metal washers 13 may be placed upon the tops of the hanger bars 2 and the nuts 10 placed on the top faces of said washers, but this construction is mechanical and may be dispensed with if desired.

For the purpose of assisting in holding the yoke, or more specifically from preventing the same fro-m slipping laterally upon the bottom or underside of the trough section, parallel ribs 14 are provided, which ribs are pressed or stamped from the channel portions of the sections. In Fig. 1 these r parallel ribs are located in pairs and the pairs are spaced from each other leaving plain portions intermediate the parallel ribs.

In Fig. 5, a slight modification is illustrated, which slight modification consists in forming the ribs 15 continuous instead of forming the ribs in pairs and spacing the same and in Fig. 6 the yoke 16 is shown angular in cross section instead of round and by so forming the yoke a suficient surface is provided to frictionally hold the yoke in proper relationship with reference to the section it comes in contact with without the aid of parallel flanges. In Figs. 7 and 8 spaced nibs 17 are punched from the channel portions of the sections and the yoke 6 located between pairs of nibs 17. The modifications shown in Figs. 5, 6 and 7 are simply mechanical in their nature as it is well understood that the only purpose is to provide some mechanical means for properly holding the yoke in position. clamping devices and the suspending devices being practically the same, regardless of the modifications shown in Figs. 5, 6 and 7.

In the maintenance of fiumes it is of importance that the proper inclination be maintained throughout the entire length of the fiumes, but the frame work supporting the fiume is liable to sag more in some places than others by reason of variations of the ground upon which the frame-work is supported, or by reason of freezing which has a tendency to disrupt the true alinement of the frame-work; and in order to provide for this variation it is of importance to provide some means by which the fiume can be maintained in true alinement or inv other words to provide means for adjusting the fiume up or down independent of the frame-work or The more specifically without disturbing the positions of the cross bars or hangers 2. In order to provide for this adjustment it is only necessary to change the positions of the nuts 9 and 10 adjusting said nuts upon the screw threaded portions upon the yoke 6, so as to permit said yoke to be lowered or elevated with reference to the cross bars 2. This adjustment either up or down can be made without disturbing in any manner the clamping bars 5.

Flumes designed and calculated for irrigating purposes are frequently formed of considerable size for the purpose of conducting a sufiicient amount of water for the purpose designed.

It is well understood that there is more or less friction as between the running water and the trough or channel through which the water flows and consequently there is considerable force brought upon the suspending trough or flume and consequently it is of importance to little resistance to the flow of water as pos sible throughout its entire length. By forming the flume sections with smooth surfaces and seating the clamping bars 5 in the channels formed at the ends of the sections very little resistance to the flow of water is offered, thereby reducing to a great extentV the strain upon the flume, owing to the fact that there is nothing in the bottom of the flume to resist or impede the flow of water save and except the continuous smooth bottom of the flume. It is well understood that in ffumes where slight ridges are located at the joints there is more or less banking of the water which greatly increases the tendency to cause the trough or fiume to move vwith the fiow of water and hence the tendency to disrupt the true alinement of the flume.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-

1. A metalflume consisting of a series of sections, the ends of the sections provided with channels and the channels of adjacent sections adapted to be seated one within the other, a clamping bar adapted to be seated in the channel of one of the sections, a yoke provided with'screw threaded portions, tie blocks mounted upon the yoke, said tie blocks provided with grooves and the ends of the clamping bar adapted to be seated in the grooves, nuts mounted upon the yoke and in contact with the tie blocks, a hanger bar and means for adjusting the yoke with reference to the hanger, substantially as and for the purpose specified.
